Home -> Community -> Mailing Lists -> Oracle-L -> Bitmap vs btree - how to tell? how to test?
Listers,
We are creating indexes on a 300m row fact table today. I am researching bitmap versus btree (again) to see where the latest info points.
Anyone care to comment on the way to determine whether an index should be a btree or a bitmap? Anyone even know a good way to test this?
thx,
/jack
